Stripe magnetism in a metallic triangular lattice antiferromagnet

ORAL

Abstract

Triangular lattice materials with antiferromagnetic interactions are a prototypical example of geometrical spin frustration and offer a platform for long-sought quantum spin liquid (QSL) states. In the presence of conduction electrons, chiral magnetic order or even chiral QSL states may emerge. Here, we present an experimental investigation of the triangular lattice compound CeLi3Bi2 through thermodynamic, electrical transport, nuclear magnetic resonance, and neutron diffraction measurements. We also perform band structure calculations obtained through density functional theory. Our results reveal that CeLi3Bi2 is semimetallic and orders antiferromagnetically at TN = 1.2 K in a stripe phase. To determine the proximity of CeLi3Bi2 to a QSL state, additional neutron spectroscopy measurements are required.
